Recently, great progress has been made in single-image super-resolution (SISR) based on deep learning technology. However, the existing methods usually require a large computational cost. Meanwhile, the activation function will cause some features of the intermediate layer to be lost. Therefore, it is a challenge to make the model lightweight while reducing the impact of intermediate feature loss on the reconstruction quality. In this paper, we propose a Feature Interaction Weighted Hybrid Network (FIWHN) to alleviate the above problem. Specifically, FIWHN consists of a series of novel Wide-residual Distillation Interaction Blocks (WDIB) as the backbone, where every third WDIBs form a Feature shuffle Weighted Group (FSWG) by mutual information mixing and fusion. In addition, to mitigate the adverse effects of intermediate feature loss on the reconstruction results, we introduced a well-designed Wide Convolutional Residual Weighting (WCRW) and Wide Identical Residual Weighting (WIRW) units in WDIB, and effectively cross-fused features of different finenesses through a Wide-residual Distillation Connection (WRDC) framework and a Self-Calibrating Fusion (SCF) unit. Finally, to complement the global features lacking in the CNN model, we introduced the Transformer into our model and explored a new way of combining the CNN and Transformer. Extensive quantitative and qualitative experiments on low-level and high-level tasks show that our proposed FIWHN can achieve a good balance between performance and efficiency, and is more conducive to downstream tasks to solve problems in low-pixel scenarios.

This paper presents a novel framework for planning in unknown and occluded urban spaces. We specifically focus on turns and intersections where occlusions significantly impact navigability. Our approach uses an inpainting model to fill in a sparse, occluded, semantic lidar point cloud and plans dynamically feasible paths for a vehicle to traverse through the open and inpainted spaces. We demonstrate our approach using a car's lidar data with real-time occlusions, and show that by inpainting occluded areas, we can plan longer paths, with more turn options compared to without inpainting; in addition, our approach more closely follows paths derived from a planner with no occlusions (called the ground truth) compared to other state of the art approaches.

图像恢复算法（例如超级分辨率（SR））是低质量图像中对象检测的必不可少的预处理模块。这些算法中的大多数假定降解是固定的，并且已知先验。但是，实际上，实际降解或最佳的上采样率是未知或与假设不同的，导致预处理模块和随之而来的高级任务（例如对象检测）的性能恶化。在这里，我们提出了一个新颖的自我监督框架，以检测低分辨率图像降解的对象。我们利用下采样降解作为一种自我监督信号的一种转换，以探索针对各种分辨率和其他退化条件的模棱两可的表示。自我设计（AERIS）框架中的自动编码分辨率可以进一步利用高级SR体系结构，并使用任意分辨率恢复解码器，以从退化的输入图像中重建原始对应关系。表示学习和对象检测均以端到端的培训方式共同优化。通用AERIS框架可以在具有不同骨架的各种主流对象检测架构上实现。广泛的实验表明，与现有方法相比，我们的方法在面对变化降解情况时取得了卓越的性能。代码将在https://github.com/cuiziteng/eccv_aeris上发布。

大多数最先进的实例级人类解析模型都采用了两阶段的基于锚的探测器，因此无法避免启发式锚盒设计和像素级别缺乏分析。为了解决这两个问题，我们设计了一个实例级人类解析网络，该网络在像素级别上无锚固且可解决。它由两个简单的子网络组成：一个用于边界框预测的无锚检测头和一个用于人体分割的边缘引导解析头。无锚探测器的头继承了像素样的优点，并有效地避免了对象检测应用中证明的超参数的敏感性。通过引入部分感知的边界线索，边缘引导的解析头能够将相邻的人类部分与彼此区分开，最多可在一个人类实例中，甚至重叠的实例。同时，利用了精炼的头部整合盒子级别的分数和部分分析质量，以提高解析结果的质量。在两个多个人类解析数据集（即CIHP和LV-MHP-V2.0）和一个视频实例级人类解析数据集（即VIP）上进行实验，表明我们的方法实现了超过全球级别和实例级别的性能最新的一阶段自上而下的替代方案。

随着深度学习的发展，单图像超分辨率（SISR）取得了重大突破。最近，已经提出了基于全局特征交互的SISR网络性能的方法。但是，需要动态地忽略对上下文的响应的神经元的功能。为了解决这个问题，我们提出了一个轻巧的交叉障碍性推理网络（CFIN），这是一个由卷积神经网络（CNN）和变压器组成的混合网络。具体而言，一种新型的交叉磁场导向变压器（CFGT）旨在通过使用调制卷积内核与局部代表性语义信息结合来自适应修改网络权重。此外，提出了基于CNN的跨尺度信息聚合模块（CIAM），以使模型更好地专注于潜在的实用信息并提高变压器阶段的效率。广泛的实验表明，我们提出的CFIN是一种轻巧有效的SISR模型，可以在计算成本和模型性能之间达到良好的平衡。

图像恢复算法（如超分辨率（SR）都是用于在劣化图像中的对象检测的必不可少的预处理模块。然而，大多数这些算法假设劣化是固定的并且已知先验。当真实劣化未知或与假设不同时，预处理模块和随后的高级任务（如对象检测）将失败。在这里，我们提出了一种新颖的框架，重新定位，以检测降低的低分辨率图像中的对象。 Restoredet利用下采样的降级作为自我监督信号的一种转换，以探索针对各种分辨率和其他降级条件的等分性表示。具体地，我们通过从一对原始和随机降级的图像编码和解码劣化转换来学习这种内在视觉结构。该框架可以进一步利用先进的SR架构的优点，该架构具有任意分辨率还原解码器以重建来自劣化的输入图像的原始对应关系。代表学习和对象检测都以端到端的培训方式共同优化。 Restoredet是一个通用框架，可以在任何主流对象检测架构上实现。广泛的实验表明，与在面对变体退化情况时，我们基于Centernet的框架已经实现了卓越的性能。我们的代码即将发布。

我们展示了拓扑转型等值表示学习，是图形数据节点表示的自我监督学习的一般范式，以实现图形卷积神经网络（GCNNS）的广泛适用性。通过在转换之前和之后的拓扑转换和节点表示之间的相互信息，从信息理论的角度来看，我们将提出的模型正式化。我们得出最大化这种相互信息可以放宽以最小化应用拓扑变换与节点表示之间的估计之间的跨熵。特别是，我们寻求从原始图表中采样节点对的子集，并在每对之间翻转边缘连接以改变图形拓扑。然后，我们通过从原始和变换图的特征表示重构拓扑转换来自动列出表示编码器以学习节点表示。在实验中，我们将所提出的模型应用于下游节点分类，图形分类和链路预测任务，结果表明，所提出的方法优于现有的无监督方法。

Graph Neural Networks (GNNs) have shown satisfying performance on various graph learning tasks. To achieve better fitting capability, most GNNs are with a large number of parameters, which makes these GNNs computationally expensive. Therefore, it is difficult to deploy them onto edge devices with scarce computational resources, e.g., mobile phones and wearable smart devices. Knowledge Distillation (KD) is a common solution to compress GNNs, where a light-weighted model (i.e., the student model) is encouraged to mimic the behavior of a computationally expensive GNN (i.e., the teacher GNN model). Nevertheless, most existing GNN-based KD methods lack fairness consideration. As a consequence, the student model usually inherits and even exaggerates the bias from the teacher GNN. To handle such a problem, we take initial steps towards fair knowledge distillation for GNNs. Specifically, we first formulate a novel problem of fair knowledge distillation for GNN-based teacher-student frameworks. Then we propose a principled framework named RELIANT to mitigate the bias exhibited by the student model. Notably, the design of RELIANT is decoupled from any specific teacher and student model structures, and thus can be easily adapted to various GNN-based KD frameworks. We perform extensive experiments on multiple real-world datasets, which corroborates that RELIANT achieves less biased GNN knowledge distillation while maintaining high prediction utility.

A recent study has shown a phenomenon called neural collapse in that the within-class means of features and the classifier weight vectors converge to the vertices of a simplex equiangular tight frame at the terminal phase of training for classification. In this paper, we explore the corresponding structures of the last-layer feature centers and classifiers in semantic segmentation. Based on our empirical and theoretical analysis, we point out that semantic segmentation naturally brings contextual correlation and imbalanced distribution among classes, which breaks the equiangular and maximally separated structure of neural collapse for both feature centers and classifiers. However, such a symmetric structure is beneficial to discrimination for the minor classes. To preserve these advantages, we introduce a regularizer on feature centers to encourage the network to learn features closer to the appealing structure in imbalanced semantic segmentation. Experimental results show that our method can bring significant improvements on both 2D and 3D semantic segmentation benchmarks. Moreover, our method ranks 1st and sets a new record (+6.8% mIoU) on the ScanNet200 test leaderboard. Code will be available at https://github.com/dvlab-research/Imbalanced-Learning.

We introduce Argoverse 2 (AV2) - a collection of three datasets for perception and forecasting research in the self-driving domain. The annotated Sensor Dataset contains 1,000 sequences of multimodal data, encompassing high-resolution imagery from seven ring cameras, and two stereo cameras in addition to lidar point clouds, and 6-DOF map-aligned pose. Sequences contain 3D cuboid annotations for 26 object categories, all of which are sufficiently-sampled to support training and evaluation of 3D perception models. The Lidar Dataset contains 20,000 sequences of unlabeled lidar point clouds and map-aligned pose. This dataset is the largest ever collection of lidar sensor data and supports self-supervised learning and the emerging task of point cloud forecasting. Finally, the Motion Forecasting Dataset contains 250,000 scenarios mined for interesting and challenging interactions between the autonomous vehicle and other actors in each local scene. Models are tasked with the prediction of future motion for "scored actors" in each scenario and are provided with track histories that capture object location, heading, velocity, and category. In all three datasets, each scenario contains its own HD Map with 3D lane and crosswalk geometry - sourced from data captured in six distinct cities. We believe these datasets will support new and existing machine learning research problems in ways that existing datasets do not. All datasets are released under the CC BY-NC-SA 4.0 license.
